How to choose doors and windows
1, the appearance should be beautiful: the paint film on the surface of wooden doors and windows should be smooth and bright, and there should be no quality defects such as sagging, bubbles, wrinkles, corrosion spots, dead joints and broken residues; The wood used for door and window covers should be in harmony with the wood and color of door and window sash. The color difference between decorative board and wood line should not be large, and the tree species should be the same.
2. The door sash should be square and should not be warped and deformed, and should be consistent with the door window frame: if the gap between the door sash and the frame is large, it is mainly because the door window frame is not allowed to be planed during installation or the door window frame is not perpendicular to the ground, the door window sash can be removed and planed again; If the door and window frames are not vertical, the gaskets in the frame plates should be aligned.
3. The hinge should be positioned accurately and installed firmly: if the hinge is not straight, it will lead to the mismatch between the door and window sash and the frame cover, and the door and window switch will not be smooth. You can unscrew a screw from each hinge first, then adjust the fit between the sash and the frame, and then tighten all the screws after adjustment and repair. If the hinge screw is short, or the screw is not screwed properly when it is screwed in, or the screw is inclined, it will lead to the deviation of the sash. Appropriate screws should be replaced and the screws must be straight. Screw in 1/3 first, and screw in the rest.
4. The door lock should be opened and locked smoothly, and the two parts locked on the door leaf and the door frame should be consistent: improper locking will lead to uncomfortable door leaf switch. The locking tongue piece should be removed, the tongue groove should be repaired with a chisel, and the position of the locking tongue opening of the door frame should be adjusted before installation. In addition, the opening direction of the door should also meet the requirements.
5. There should be substrate in the door and window cover: when the window cover is joinery board or density board, the substrate board should be fixed on the base keel of the window frame first, and then the thread should be nailed: the door cover should be made of wood, then planed and straightened, then assembled and installed on the wall, and then covered with substrate board and decorative board. Tap the side plate of the door and window cover by hand. If there is an empty drum sound, it means that there is no foundation board such as joinery board at the bottom, so it should be folded and redone.
